Maimonides Substance Quotations

No form remains permanently in a substance; a constant change takes place, one form is taken off and another is put on.

Now I wonder what our knowledge has in common with God's knowledge according to those who treat God's knowledge... Is there anything else common to both besides the mere name? ...there is an essential distinction between His knowledge and ours, like the distinction between the substance of the heavens and that of the earth.

Transient bodies are only subject to destruction through their substance and not through their form, nor can the essence of their form be destroyed; in this respect they are permanent.
